A literal translation of the Greek text -
Eph 5:13
But all things (τὰ δὲ πάντα) being rebuked (ἐλεγχόμενα, present passive participle) under/by the light (ὑπὸ τοῦ φωτὸς) are being made manifest (φανεροῦται, present passive indicative): for the thing being manifested (γάρ τό φανερούμενον, present passive participle) light (φῶς) is (ἐστίν).5:13 τὰ δὲ πάντα ἐλεγχόμενα ὑπὸ τοῦ φωτὸς φανεροῦται πᾶν γάρ τό φανερούμενον φῶς ἐστίν
Eph 5:14
Through which he is saying (διὸ λέγει, present active indicative), "Start waking up (Ἔγειραι, aorist active imperative) the one sleeping (ὁ καθεύδων, present active participle), and start standing up (καὶ ἀνάστα, second aorist active imperative) out from the dead ones (ἐκ τῶν νεκρῶν), and He shall give light (καὶ ἐπιφαύσει, future indicative active) to you ( σοι) the Christ (ὁ Χριστός).5:14 διὸ λέγει Ἔγειραι, ὁ καθεύδων καὶ ἀνάστα ἐκ τῶν νεκρῶν καὶ ἐπιφαύσει σοι ὁ Χριστός
Eph 5:15
Keep on watching therefore (Βλέπετε οὖν, present active imperative) how (πῶς) circumspectly (ἀκριβῶς), you are walking (περιπατεῖτε, present active indicative), not as fools, (μὴ ὡς ἄσοφο) but as wise (ἀλλ᾽ ὡς σοφοί),5:15 Βλέπετε οὖν πῶς ἀκριβῶς περιπατεῖτε μὴ ὡς ἄσοφοι ἀλλ᾽ ὡς σοφοί
Eph 5:16
Redeeming (ἐξαγοραζόμενοι, present passive participle) the time(τὸν καιρόν), because (ὅτι) the days (αἱ ἡμέραι) evil (πονηραί) are (εἰσιν). 5:16 ἐξαγοραζόμενοι τὸν καιρόν ὅτι αἱ ἡμέραι πονηραί εἰσιν
Eph 5:17
Because of this fact (διὰ τοῦτο) do not keep on becoming (μὴ γίνεσθε, present middle deponent imperative) unwise (ἄφρονες), but (ἀλλὰ) become understanding (συνιέντες, present active participle) what (τί) the will (τὸ θέλημα) of the Lord (τοῦ κυρίου) is.
5:17 διὰ τοῦτο μὴ γίνεσθε ἄφρονες ἀλλὰ συνιέντες τί τὸ θέλημα τοῦ κυρίου.
My own paraphrase of the sense of the Greek text -
5:13 But all things that are being rebuked are being exposed when put under the spotlight; for the thing really being exposed is light itself, 14 through which God is saying to the evildoer,
"Wake up, sleeper, and stand up out from those who are dead and Christ shall give light to you."15 Therefore, keep on watching how carefully you are walking, not as fools but as those who are wise, 16 redeeming the time, because these days are evil. 17 And because these days are evil, stop becoming unwise stewards, but become stewards who understand what the Lord's will is.
1. " But all things that are being rebuked are being exposed when put under the spotlight ..."
Rebuking unbecoming behaviour that falls short of God's intended glory for mankind, exposes the behaviour to examination as to whether it conforms to Gods word.
2. "... for the thing really being exposed is light itself..."
In highlighting misbehaviour we are not really aiming to make the sin the star of the show, the centre of attention. we are bringing God's measure of righteousness and truth to the forefront and comparing the misbehaviour to what God says is good. I am to compare the bad behaviour to the truth of God's word, and not just criticise on the basis that I find the behaviour offensive.
3. "... 14 through which God is saying to the evildoer., 'Wake up, sleeper, and stand up out from those who are dead and Christ shall give light to you.' "
My highlighting the light of God's truth is, to the dead to the Spirit evildoer, like opening the curtains so that sunlight streams into the bedroom disturbing a dead-to-the-world sinner's daytime slumber. By opening the curtains and shining upon him the light, I am saying,
"Wake up, sleepyhead! Get up and the sun will give you the light you need to get things done.
Pro 6:9
How long will you sleep, O sluggard? when will you arise out of yoir sleep?
Pro 6:10
Yet a little sleep, a little slumber, a little folding of the hands to sleep:
Pro 6:11
So shall thy poverty come as one that travels, and your want as an armed man.
Isa 60:1
Arise, shine; for thy light is come, and the glory of the LORD is risen upon yoiu.
Isa 60:2
For, behold, the darkness shall cover the earth, and gross darkness the people: but the LORD shall arise upon you, and his glory shall be seen upon you.
Isa 60:3
And the Gentiles shall come to your light, and kings to the brightness of your rising.
4. "15 Therefore, keep on watching how carefully you are walking..."
We are to monitor continually how careful we are to walk in truth, in a God-pleasing way.
5. "... not as fools but as those who are wise, 16 redeeming the time, because these days are evil. 17 And because these days are evil, stop becoming unwise stewards, but become stewards who understand what the Lord's will is."
cf. Luke 12:35-48 The Christian should be careful to be found busy at His coming doing the Father's business. I should not let Him find me skiving, neglecting what is important for the growth of the Kingdom in favour of time-wasting diversions.
